Description:

Stubs out new asset placeholders. Pass the asset name, either CamelCased
or under_scored.

To create an asset within a folder, specify the asset's name as a
path like 'parent/name'.

This generates a JavaScript stub in app/assets/javascripts and a stylesheet
stub in app/assets/stylesheets.

If CoffeeScript is available, JavaScripts will be generated with the .coffee extension.
If Sass 3 is available, stylesheets will be generated with the .scss extension.

Example:

`rails generate assets posts`

Posts assets.
    JavaScript:     app/assets/javascripts/posts.js
    Stylesheet:     app/assets/stylesheets/posts.css
